I'm waiting for the pics

Yes, that's a very good question about FRS actually. Here is a little more info as I understand it.

FRS (Family Radio System) radios use FM modulation just like popular VHF/UHF Amateur Radio transceivers (Ham Radio). This generally sounds a lot better than the SSB modulation used by CB (and some other Amateur and Government) radios, although SSB is more efficient and can go farther on its on (without use of repeaters).

Technically, one can at least receive and even transmit on FRS frequencies with Amateur Radio equipment, although the transmitting part would be illegal except in the case of emergencies.

Here are the specific FM frequencies used by FRS radios:

Channel No. (MHz)

1................... 462.5625
2................... 462.5875
3................... 462.6125
4................... 462.6375
5................... 462.6625
6................... 462.6875
7................... 462.7125
8................... 467.5625
9................... 467.5875
10.................. 467.6125
11.................. 467.6375
12.................. 467.6625
13.................. 467.6875
14.................. 467.7125

That was easy to find using Google and was from:
http://www.panix.com/~clay/scanning/...cies/frs.shtml

By comparison, on of the many Amateur Radio bands goes all the way from 420 to 450 MHz, just below those. Amateur Radio transceivers (including home-made equipment) can transmit in that range using a huge amount of power and antenna combinations -- up to 1500 watts out of the transmitter even before antenna gain is applied. The rules allow that much power but typically 30 watts or less is used (and adequate for line-of-site purposes).

That same web page says the maximum power (ERP, Effective Radiated Power) for FRS radios is just 0.5 watts. So, they're pretty limited in range because of that and because repeaters and linking is not available.

Fun...

That's regarding the previous posting:
stupid question, frs hand radios, do they communicate with CBs or is that a different frequency... Thanks for the help.


Thanks for the comments about running coax and installation on the H3!

What is the recommended CB for the most output,
I noticed that alot of Truckers seem to be running high power. I can pick up on Them from a distance, but they can't read me if I respond.
Yes, I bought a Radio Shack 40 channel, Trc-521. I still have 25 days to return.
thanks.

I believe 4 watts is the max power for Close Band. Its been awhile since I got my ham (KD7SNA) You might be recieving them because their antennae is alot higher than you are off the ground, and much longer as well. Probaby you wont get that much better performance from a diffrent rig.

i bought a radio shack special several years ago, and attatched a cig adapter power thing to it so its portable, and bought a magnetic antenna... the cb works great but mounting the antenna on the roof makes it hit all the trees and fall over... so i finnally just took it out of my rig during the last trail ride..

ok lets give this a try:





sorry for crappy pic quality....

So, I guess to solve this question, Size is really everything, I mean antenna highth/length that is. Now I'm getting the Picture.

Hey k9tim ... how do you have the 706 mounted? looks a little tight with the ex. speaker does your leg hit it at all? icom makes a great rig and I had one of the first 706"s when they came out years ago ... tnx, kf4fjf

Well, height and length does mean everything (for the most part). Best case scenario would have my antenna on the top of the truck, but then I would have to get out and fold it over to pull into my garage.
The basic rule of thumb is the longer it is the better it is provided it is a length that is 1/4 wavelength, 1/2 wavelength, blah blah blah.
Gets a little complicated.

@h3humvee- I used a lo boy mount that I bought at HRO. here is a link to the manu: http://www.pro-fit-intl.com/loboy/

They have a bunch of different options, all using adhesive tapes for easy removal later. My knee can hit the rigs face at times but I can actually move it over more towards the center of the console by another 2 or 3 inches, I just havent got around to it yet. The speaker is totally out of the way and the rig body is under my drivers seat.
It looks kinda tight (and it is) but its also hard to see from the outside of the truck

The only bad part about it is that I wear polarized sunglasses so if I dont look at the display at the right angle, it vanishes. A lil annoying sometimes.

Yep the 706 is a sweet rig- Kinda cool cruising around and talking to places like South Africa when conditions are good

Anyone intersted in Amateur Radio should visit http://www.arrl.org. That will get ya started!

Hey H3humvee-

You just renewed your ticket- saw it is Adv class- thought that wasnt around anymore? Did it just renew with the old class?

I'm a lil rusty on classes & op privledges and I know things changed a few years back..Fill me in if you would...you can always mail me at:

My Amateur Radio license KK7DV is Advanced class too!
(Use http://www.qrz.com to lookup call signs.)

It was back from when I had to pass a more code
reception test at 13 words per minute. Pretty fun,
kind of like learning to play "Dance Dance Revolution"
which I have done recently with the Mario Mix
GameCube game -- That's good exercise by the way.
This is really getting off-topic, sorry!

Excellent on the contact with South Africa, K7TIM...
For the info of others, this HF communication we're talking about
involves signals that go right from K9TIM's radio in his Hummer,
bounce off the ionosphere once or twice and around the world
without the help of any repeater or Internet linking system.
(But, it's also fun to use Internet links to talk to
countries like South Africa and Australia with super clear
quality and always-available reliability, at no cost.)

yeah, I'm a little rusty to ..I started out getting my technician license which was a written test then after passing the 5 word per minute code I upgraded to a tech plus ... when I got my general operating license you had to pass a written test as well as receiving 13 words per minute and when I went for my advance license it was a written test and receiving 20 words per minute ... I have forgot most of the code because I never use it but in a pinch I could communicate using it if I had to.

Yes, one more Question, in Regards to the Happy Jack Video H2- Ken p/h2- co That H2 has 2 antennas, will 2 antennas strengthen my imput/ output. Pictures to be posted soon, After I finalize, so far so good.

You will need to google it unless someone here has the numbers but if he has 2 cb antennas, that means they are phased.
It will affect your receive and transmit BUT they need to be spaced apart at the right distance otherwise they will do more harm than good.

If memory serves me right (and it usually doesnt) the gap between phased CB antennas should be around 9 feet.
One of the other radio guys may have the formula handy and can figure it out for 27mHz.

If it is around 9 feet then obviously you would be talking about mounting one at the front and one near the back of the truck.. kinda lame looking.
Personally I would stick with one and just buy a higher quality antenna. Something with a little higher gain than a cheapy whip.
Hope that helps!

I found some good tech info on Firestik's site when I was installing mine.
